Use of Flow-through Samplers to Measure Near-field Vapour Drift of Fungicides
Pesticides play an important role in maintaining crop health; but pesticide losses due to volatilisation reduce the pesticide s efficiency and contribute to environmental contamination. Current methods for measuring vapour drift usually use highvolume air samplers, which are expensive and require network power, limiting the number and type of sites where they can be deployed. An alternative type of air sampler, called a flow-through air sampler (FTS), has recently been developed and used to measure longrange atmospheric transport of contaminants, but has not been tested in near-field pesticide vapour drift studies. The FTS is a passive sampler that turns into the wind like a wind vane and uses the Venturi effect to draw air through its sampling media.
